Darwin suggested looking at a species' close relatives to learn what its ancestors may have been like. how does his suggestion anticipate recent methods, such as phylogenetic bracketing and the use of outgroups in cladistic analysis?

It is to deduce the probability of obscure attributes in life forms in view of their position in a phylogenetic tree. One of the primary utilizations of phylogenetic sectioning is on wiped out creatures, known from fossils.
